Overview of Higgs Factories

The Higgs boson was discovered in 2012 by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) in Geneva, Switzerland. This particle plays a unique role in fundamental physics. It gives mass to all of the known elementary particles, including the Higgs boson itself. While we now have strong evidence that the Higgs field is indeed the unique source of mass for the known elementary particles, the next step is to search for new interactions that could also explain why the Higgs field has the properties required by the Standard Model of particle physics. While there is no clear roadmap to this new theory, the Higgs boson plays a crucial role in this quest. The goal of a Higgs Factory - consisting of the collider facility and the related experimental detectors - is to carry out precision measurements to the per-cent level of the Higgs boson properties that are not accessible at the LHC. In this talk we present an overview of Higgs Factories and their current status.
